In February 2025, Caglayan Vural developed a volume-tracking adapter for the 1delta protocol on the Fuel network within the DefiLlama/dimension-adapters repository. He focused on expanding on-chain data coverage by enabling daily volume ingestion from the Fuel subgraph, supporting both subgraph URL and API key-based authentication for flexible deployments. Using TypeScript and leveraging full stack development and API integration skills, Caglayan ensured the adapter integrated cleanly with the existing suite. The work addressed the need for timely and complete DeFi volume metrics across networks, with an emphasis on reliability and maintainability, and no major bugs reported during the period.
